ROLLER SUPPORT FOR ROTARY DUMPS.

Application filed September 6, 1927. Serial Ne. 217,810.

My invention relates to rotery cer dumping epperutus, more particularlyto the supporting means for such epparetue, and hes for its object theprovision of animproved roller support upon which the dump :is

edepted to rotzte'us it operzrtes. p

More speeficelly the ob1ectof my invention is to provide an improvedroller support including rollers having hearing portiene of differentdiumeters whereby o relatirely wide &ngulur movement of the part el'-greeter diameter may be obteined with respect to the &ngulur ot smallerdiameter.

It hee been the practice heretotore to pro- Vide rotery dunpe withriding ringe which were `Supported either upon rollers nounted movementof the part i on u fixed enis or upon rollers restng on e truck orsupport and having both bodily end mguhr movement responsve to therqtetion My present nventon roller supports and its prime object is` toreduce to :L 'minimum the travel o'l' the roller support und to eiu'plily and perfect the track elemente both on` the roller support and on theriding ring ol the rotery dump with which the roller& co-ect. Ii'rorderto reduce 'the linezl travel ot therollers, I provide a ditereutiulroller having its larger diameter portion co-icting with the rotory dumpand 'its Smaller diameter portion co actng with the fixed truck orsupport, whereby Wide peripherul travel of the large diameter ridingrings is red uced to e Very small lineul travel oi' the roller on itstruck supports.

My inventiou 'Eur'the' contempletee so de- Signing the ditlerentizrlroller and 'its'trnck eupporte that itie beleuced in its work and willserve 'to hold the ridiug ring of the dump in correct position centrollyabovethe track.

My nventon further contemplutes the designing; of both the trucksupports and the 'riding ring of 'the dump and the working surtucee otthe d'iffereutial roller so that all :rre protected by case herdenedsteel, thereby "providing great durability. i i i 1:\pperetue embodying'Features of my `in- `Veiuion is "illuerzted in the uecomprrnyingdrewings forn'ing u port of this epecificeton, Wh erein i Fig. 1 ie enend elevetion of` a rotury dump provided with 'my improvedrollersupports. p i i i i i l Fg.

wear of both the rings and the bearings, is provided with-a track 41,preferably made of case hardened steel, and extending around the channelmember to form a hearing surface therefor.

The hearing members 33 and 34 are mainjtained in spaced relation bymeans of a segmental frame comprised of similar front and rear framemembers 46 and 47. The members 46 and 47 are provided with holes 48 and49 to accommodate pins 51 and 52 extending through the holes and throughsuitable holes provided in the axle portions 38 of the 'bear- 'ings Thepins 51 and 52 are held in place with respect to the hearing by means ofplates 53 secured to the member 46 by cap screws 54 and extending intosuitably formed notches in the pins 51 and 52. The members 46 and 47 areheld properly sp'aced by means -of a pair of short channels 56 and 57`arranged It 'will be seen from a consideration of Fig. 1

that the members 46 and 47 hold the bearings 33 and 34 in properlyspaced -relation at :in

:times The travel of the bearings islimited'at each end of the track by'means of a curved stop 61 form'ed at .the uppervend of each of thetrack members, so that when either of the bearings reaches the stopitsaxle portions are engaged thereb and it is'prevented from further travelThespacing of ,the bearings 33 and 34 and the arrangement'of the stops61,

as will be seen from Fig. 1, are such that the bearings areat all timeslisposed on opposite sides of the central verticalplane passing throughthe riding rings 16.

i In order -to protect the bearings 33 and 34 and the tracks ;36 and 37from beingclogged with material when 'the cars are being i dumped, Iprovide the members 46 and 47 with inwardly extending lip portions '63and' rotation of the riding rings16, when dumpi ing the cars, thebearlngs 33 and 34 are rotated by their contact with the riding rings i16. Inasmuch as 'the axle portions 38 of the (with the stop 61.

V bearings bear upon the tracks-36 and 37, the

lineal movement of the bearings is obviously ?much less than that of therings 16. Assum- :ing that the rings 16 are to be rotated to the left,as 'shown by the arrow iniFig. 1, a rotation of approximately 180degrees thereo'f will only cause the-bearings to move `until the thea'xleportion'of the bearing 34 is engaged `The advantages of theihereinbefore de scribed Construction will be clearly appreciated inthat it affords a hearing support remarkably free from fr iction, andhence having a long life, and one which insures a proper support 'or theriding ring, whatever the angular movement 'of the dump.

lVhile I have shown my invention in but one form, it will be obvious tothose skilled in the art that it is not so limited, but is susceptibleto various changes and modiieat ions, without departing from the spiritthereof, and I desire, therefore, that only such limitations shall beplaced thereupon as are imposed by the prior art or as are specilicallyset forth in the appended claims.

Having thus described my invention, what Iclaim as 'new and desire tosecure by Letters Patent, is

In apparatus of the character described, a riding ring, a segmentaltrack arranged beneath the ring, a plurality of movablc rollerbearingsonthe trackand supporting the ring and adapted upon angularmovement of the ring to roll along the track, said bearings each havingan axle portion hearing on the track and a'body portion supporting thering, the body portion being of greater diameter than the axle portion.
